That is Kṛṣṇa consciousness. If he takes to Kṛṣṇa consciousness, that is his actual life. Otherwise, he's in the dreamland. Daivī hy eṣā guṇamayī mama māyā duratyayā (BG 7.14). This is called māyā, illusion. Nighttime dreaming and daytime dreaming. The nighttime dream... In this way, we are dreaming life after life. As human being, as animal, as tree, as aquatics. Jalajā nava-lakṣāṇi sthāvarā lakṣa-viṁśati. This evolutionary process is going on.
Therefore, therefore Caitanya Mahāprabhu says,
- ei rūpe brahmāṇḍo bhramite kono bhāgyavān jīva
- guru-kṛṣṇa-kṛpāya pāya bhakti-latā-bīja
- (CC Madhya 19.151)
The living entity is wandering in this way, life after life—sometimes as human being, sometimes as demigod, sometimes as brāhmaṇa, sometimes as śūdra, sometimes as tree, sometimes as insect, sometimes as fish, so many. Sometimes as birds. And in different planets also, not only in this planet. Brahmāṇḍo. Therefore Caitanya Mahāprabhu says, brahmāṇḍo. Within the universe, he is traveling according to his karma.
- yānti deva-vratā devān
- pitṟn yānti pitṛ-vratāḥ
- bhūtejyā yānti bhūtāni
- mad-yājino 'pi yānti mām
- (BG 9.25)
So those who are in goodness, they are being promoted to the higher planetary systems of demigods.
